Description

Bunker Alfa is one of several Army bunkers that can be found on the Global Map. It consists of a ground-floor level and four underground sub-levels that can be accessed via a passcode (obtainable from dead soldiers in resource areas or with CB Radio). The underground floors can be quite difficult for lower-leveled players, therefore it's a good idea to bring decent armor and weapons to these floors. This is doubtly true for hard mode.

Bunker Alpha Description

Venturing into the bunker's lower levels can be quite lucrative for those who are capable of surviving its dangers. In addition to loot-filled reward chests, the bunker also offers a method to modifying firearms and unique enemies.

Note: Location available from level 15

Features

There are several features that are unique to Bunker Alfa, such as modified zombies, turrets, the coupon exchange system, and special objects or rooms.

Creatures

Unlike their counterparts outside the bunker, some of the zombies in the sublevels have unique traits. Most notably, they do not use special attacks, and they have altered (usually reduced) sight ranges, including attacking the player in groups if one is alerted. They also do more damage than zombies outside the bunker.

Enemies In Bunker Alpha

Infrastructure and Security

  • Electrified Fence: This does damage to the player at a very high rate when in contact. 5 damages dealt, but high rate, and could be also kill you in 1 second! Found only on floor 3.
  • Elevator: This allows movement to other floors. Each floor loads as a separate zone.
  • Generator: (Nonfunctional in current versions, and may change in the future update) In previous versions, activating generators was necessary to provide power for access to lower sublevel floors. Found only on floor 4.

GENERATOR RECHARGE
It will take time to restore electricity supply to
lower floors. When the generator works at its
full capacity, you'll be able to get there in the
elevator. - 4th floor generator message

  • Laser Tripwire Alarm: Crossing these lasers sounds an alarm that alerts a group of nearby enemies to the player's presence. Can be turn off using Terminal. Found only on floor 3.
  • Terminals: Accessing computer terminals performs various actions such as remotely opening doors or turning off laser tripwire alarms. Found on all floors.
  • Turret: An automated turret attacks the player once in range. It has 250 HP, a 360-degree attack radius, and range approximately equivalent to the Glock 17. Turrets have 15 armor rating that reduces incoming damage by half: it only takes 53% damage . These turrets do not attack zombies, but shoot you and his range increases when he already shoots you
  • Heavy turret: Appears on 4th floor only. It has 500 HP, a 360-degree attack radius, a 45 armor rating that reduces incoming damage by three-fourths: it only takes 27% damage, and range approximately equivalent to the normal turret. Heavy turrets not only shoot but also launch grenades (like the Milkor MGL) at you. These turrets do not attack zombies and his range increases when he already shoots you.

Other Hazards

  • Gas Chamber: This is a room entirely filled with poisonous gas. The gas does damage to the player at a very high rate unless they are equipped with a Gas Mask (which absorbs damage while exposed to gas, but break if used in long time). Found only on floor 3.
  • Gas Leaking from Pipes: Some areas contain gas bursting from pipes. This gas does damage to the player at a very high rate. Depending on the location, some pipes can be shut off from a source valve, or the gas may only leak at periodic intervals and can be passed if timed properly. Additionally, the Gas Mask can be equipped to protect the player from damage, as in the Gas Chamber. Zombies are immune to the effects of gas. Found on floor 2 and 3.
  • Gore: Gore is usually indicated by a red-colored area on the Minimap.(They won't show up now) The effect on the player is to reduce their movement speed while in these areas by approximately half; zombies are unaffected. Additionally, in some halls with arms protruding from walls, contact with the arms will cause 3 damage to the player. These arms do not damage armor.

Upper Level

Bunker Alfa.PNG

The outside area of the main level contains 17 Pine Trees and a lootable corpse with a half-used Glock 17 in its inventory. First-time access to the Bunker's interior requires a CAC Card A, which is possible to be acquired from loot or enemies at various zones on the Global Map. After using the access card, this area will remain unlocked permanently.

With update Beta v.1.8, a minigun drop was added in a cage against the exterior wall of Alfa, only accessible with a Rank IV True Friend dog.

Inside, there are no zombies but several lockers containing useful Items. These items on the upper level do not reset. While this prevents returning for new loot, it allows the area to function as a storage location separate from the player's home. There are seven separate Military lockers with 20 slots.

Code

Screenshot 2018-07-26-17-01-26.png

To access the sublevels of Bunker Alfa, a passcode must be entered into the computer terminal in the main building on the ground floor. This passcode changes every two days and must be manually entered every time the bunker resets (48 hours after it was last opened). The code is shared between all players on a particular operating system (Android and iOS users have different codes) and can be found at the following locations:

  • CB Radio: This furniture can be built in your home base, and an exclamation point "!" icon or a number "2"/"3" (Dependent if you have the Raider and/or the Dealer Joe on the radio) will appear over it to notify you of a new daily code. Tune it to the correct frequency to view the new code. After 2 days, the door closed, and it uses the new codes.
  • Dead Soldier: This corpse can be found in resource zones and appears as a red "X" on the Minimap in those zones. Upon looting this corpse, a dialogue box will appear with the current code. These soldiers do not have any items.
  • Can be learn at Last Day on Earth: Survival official Discord server.
  • LDOE code : This application can be downloaded from Google Play which retrieve the code from this page. It has no ads.

  • Note: lower floors only acessible since Beta v.1.5 July 24, 2017

"More Power" Error Message

On some mobile devices, if you attempt to input the passcode into the bunker's terminal, you will receive the following error message: "It seems that the device needs more power." This means the mobile device on which you are playing the game does not meet the minimum specifications to handle the lower levels of the bunker. Although recent optimizations will reduce the number of players who see this message, for some players, it may be time for an upgrade!

Sublevels

The sub-levels of the Bunker functions differently from the ground floor. A unique code that changes every other day is required to access them. Once the terminal is activated, an entrance appears and a unique instance of the sublevels is created which lasts for 48 hours (from the time of opening) before reset.

During this period, all progress is saved including enemies killed, items looted, and the corpse of the last player death. Upon reset, the sublevels can be revisited with a new code. All enemies will have respawned and items will be reset. As of version Beta v.1.5.6, the primary method of obtaining the most valuable Items is via a coupon-exchange system.

Floor 1 - Lobby

The first sublevel serves as a "lobby" area and contains several features related to the lower areas of the bunker. A notable feature of this floor is the Coupon Exchange terminals, which can be used to obtain loot-filled reward crates. There is also an Army Specialist who can be rescued at the end of the second sublevel and will return to the lobby and unlock the Overseer Room, where he will offer several benefits to the player. 6 zombies spawn here (5 Fast Biters and a Floater Bloater)

Locked door: The stuck door near the green coupon crate distribution gate became a doggy door (A dog with the skill True Friend is required) with update Beta v.1.7.9. However, this was removed with the update Beta v.1.8. Since Beta v.1.9.8 you can open this door by using a Cut Finger.

Coupon Exchange: Coupons for the reward terminals can be found on the corpses of defeated Creatures and from boxes/lockers in the bunker. Additionally, coupons have a low chance of being found outside the bunker (red zones, airdrop events).

Rationing Terminal.png
Rationing Terminal (16 items): 20 green coupons are required for each Ration Box. Each Ration Box has a chance of containing food, weapons, parts, medicine, resources, and simple protective clothing but may contain none of them.

Survival Kit Terminal.png
Survival Kit Terminal (17-20 items): 25 yellow coupons are required for each Survival Kit. Each survival kit has a chance of containing guns, vehicle parts, medicines, refined resources, military clothing, and gasoline but may contain none of them.

Combat Gear Terminal.png
Combat Gear Terminal (26-29 items): 30 red coupons are required for each Combat Gear Box. Each Combat Gear Box (by far the best in terms of gear) has a chance of containing modified weapons, heavy firearms, vehicle parts, high-grade military gear, coloring patterns, rare resources, and Gasoline (But the Gasoline is rare in the Combat Gear Box).

Overseer Room

  • The bunker's Hard Mode can be activated in this room. This is not recommended for inexperienced or under-geared players.
  • The Specialist will accept Identification tags, Chevrons, and Military Notebooks (can be obtained when killing zombie when hard mode is activated), rewarding the player with reputation, which unlocks new weapons, firearm modifications, and Floppy Disks.
  • Each level of Reputation requires 140 points; Identification tags are 1 point, Chevrons are 2 points, and Military Notebooks are 3 points, there is no max level for the Specialist yet but the level visually stays at level 15. You will continue earning floppy disks after the Milkor MGL.
  • The Specialist will get Blueprint exchange Weapon mod blueprints get common modifications, rare modifications, extremely rare modifications, extremely rare mod with active skill.
  • The Tactical Terminal uses the Floppy with coordinates to give the location of a valuable loot crate or an Infected Box (creating a new, limited-time event on the Global Map).

Floor 2

Notable features on Floor 2 include gas leaking from pipes (some of which can be shut off by a valve), gore areas, a terminal-controlled door, a turret, and Frenzied Giants, among other enemies. There is also The Big One locked in a lab on F2, but he can only pace from side to side--he cannot attack. Added in Beta v.1.9, a Weapon Modification Spot, you can modify your weapons without having to go back to your base.

B2F = 8 Roaming Zombies, 13 Fast Biters, 5 Toxic Spitters, 8 Floater Bloaters, 5 Toxic Abominations, 7 Frenzied Giants, 1 Turret

Floor 3

Notable features on Floor 3 include an electrified fence, a gas chamber, gas leaking from pipes, a generator was removed in Beta v.1.7.9, a gore area, terminal-controlled doors and laser tripwire alarm, and a turret. Additionally, the Acid Bath blueprint can be learned from a drafting table in one of the final rooms.

B3F = 4 Fast Biters, 25 Toxic Spitters, 1 Floater Bloater, 16 Toxic Abominations, 10 Frenzied Giants, 1 Turret

Floor 4

Notable features on Floor 4 include 3 cold rooms (2 of which contain a new type of indestructible Spike mine trap (8 total), 2 terminals, 1 generator, and 2 doggy doors (A dog with the skill True Friend is required). Loot on this floor may include copper ore and bars or steel, as well as turret parts.

B4F = 7 Fast Biters, 6 Toxic Spitters, 1 Floater Bloater, 5 Toxic Abominations, 3 Frenzied Giants, 3 Turrets, 3 Heavy Turrets, 7 Numb Zombies, 3 Frozen Bloaters, 8 Spike mine traps

Sublevels - Hard Mode

Following the activation of hard mode in Bunker Alfa, an alarm sounds and the lights strobe red. While hard mode is active, creatures generally drop reputation items instead of coupons, with similar values and frequencies. During hard mode, creatures hit harder and have higher defense against attacks;

  • Small Zombies have 15 damage (10 in normal) and gains 15 armor while Big Zombies have 30 damage (20 in normal) and gains 20 armor.

There are also some creatures that only appear in Bunker Alfa during hard mode. [Also applied to Turret, which does 30 damage (20 in normal)]

Floor 1 - Lobby - Hard Mode

The lobby is unchanged after hard mode is activated; neither creatures nor crates reset. Hard mode activation is irreversible until the code activation of the entire subterranean complex expires at the end of its two-day window. After the bunker fully resets, it will return to normal mode when the new code is entered.

Floor 2 - Hard Mode

Notable features on Floor 2 during hard mode include all the security and infrastructure features of normal mode, plus buffed zombies, some Toxic Abominations replaced by Exploders, and high-speed Frenzied Giants. There is also The Big One locked in a science lab on Floor 2, but he can only pace from side to side--he cannot attack.

B2F = 8 Roaming Zombies, 13 Fast Biters, 5 Toxic Spitters, 8 Floater Bloaters, 2 Toxic Abominations, 3 Exploders, 7 Frenzied Giants, 1 Turret

Floor 3 - Hard Mode

Notable features on Floor 3 during hard mode include all the security and infrastructure features of normal mode, plus buffed zombies, some Toxic Abominations replaced by Exploders, high-speed Frenzied Giants, and The Blind One. The Blind One is located in an outer room with an activation console and hanged scientist After entering the room the door closes since version Beta v.1.10.

B3F = 4 Fast Biters, 25 Toxic Spitters, 1 Floater Bloater, 4 Toxic Abominations, 12 Exploders, 10 Frenzied Giants, 1 The Blind One, 1 Turret

Floor 4 - Hard Mode

Notable features on Floor 4 during hard mode include all the security and infrastructure features of normal mode, plus buffed zombies, some Toxic Abominations replaced by Exploders, and high-speed Frenzied Giants.

The cafeteria and starting room areas are the best and most likely only places (excluding the soon-to-come doggy-door zones) where it is easy to kite around Exploders, Frozen Bloaters, and Frenzied Giants. Take advantage of these rooms to make it as easy as possible to kill them.

B4F = 7 Fast Biters, 6 Toxic Spitters, 1 Floater Bloater, 2 Toxic Abominations, 3 Exploders, 3 Frenzied Giants, 3 Turrets, 3 Heavy Turrets, 7 Numb Zombies, 3 Frozen Bloaters, 8 Spike mine traps
